My goal is to have the same shortcut to trigger apps that I use most of the time, that start with the exact same letter (since spotlight sometimes gets slow or it shows other results and I want to go straight to the app). For example
They all have the shift+alt+p trigger, hence the conflict window. So it's super fast (compared to spotlight). But since I'm typing the letter, using the arrows would be faster than moving my hand to the mouse, drag the cursor, click the app's name. You know what I mean? It's just a better workflow for me.
If BTT had a more active community, I wouldn't mind keeping both apps, but it's pretty silent there. It's very hard to get any feedback or help. And to be honest, most stuff I can do with BTT, I can with KM, so to me it just makes sense to only use KM and then only use BTT for stuff KM can't do (or at least, I think KM doesn't do)
